Managing Partners 

Johann Entz- von Zerssen: I understand my role to be the assistant to my clients and customers to step into the space of their ‘being’ wholeheartedly, to be able to face the challenges life throws at them every day. Over the past 20 years, I have come to understand how difficult and yet possible change for individuals and teams is once awareness and a willingness to address these challenges have surfaced. In my work, I make use of eclectic and tested approaches based on developmental, systems, and complex adaptive systems theory and practice. My aim is to find a healthy balance for my clients between doing and being in the way they make decisions, overcoming learned resistances, integrating ‘immunities to change’ and thus becoming more authentic in their own personal development and in the way they show up in the world. I am a professional certified coach (PCC) and work as faculty for coach training for the Coactive Training Institute (CTI). 

Anne Caspari, MSc: My specialty is transformational processes in all contexts, personal and organizational, long before it was called change management. Having studied ecology and having worked with ecosystems in the past, I can rely on a solid body of knowledge of how complex adaptive systems work and what tends to get in the way of self-organizing processes. Adding humans to the equation, these processes become even more complex and unpredictable for decision-makers and leaders. Where most change methods and theories promote an overly simplistic approach to transformative processes, I facilitate change from a deep understanding of how we can overcome resistance to change, and how to nudge human systems in a more generative direction from within. This work is deeply rewarding. It is completely practical and hands-on, yet based on adult development, complexity, and cognitive science. 

Hannes and I both operate from Germany. We are both certified in the use of the Leadership Circle Profile TLC; Lectica’s Decision Making Assessment LDMA, and The SenseMaker-Software and are part of the 5 people worldwide to conduct the Cynefin Base Camp courses for the Cynefin Company (Cognitive Edge).

Mushin  J. Schilling:  International Software architect and consultant, change agent since 1988. Consultant with an emphasis on organizational development and strategy and personal change.

Expanded Team

Tomáš Hančil, PhD

My work is rooted in developmental psychology and focuses on both organizations and individuals. I am using an interdisciplinary approach, combining psychology, philosophy, and natural sciences with management studies and theology. The questions I am trying to answer are: how can we make correct decisions in today’s complex world and how can today’s leaders be more effective in their everyday work. I am proud and honored to be part of the developmental journey of my clients. I firmly believe that personal growth is as difficult for a top manager of a multinational company as it is for a plumber. Personal maturity and practical wisdom are not dependent on social status. That is why I am focusing on personal development and particularly on how people think. We are now certain that the effectiveness of leadership is not based on technical skills or processes. The effectiveness of leaders is based on their ability to grow as people.
